WINDOW p Gumn.

Application mea December s, m24. serial 110.754,515.

State of Massachusetts, have invented an Improvement in Window Guides, of which the following is a specification.

` This invention relates to that class of guides for 'the Window glass in automobiles in which. the guide is` made entirely .of metal, a guide of this character being disclosed in my prior Patent #1,374,629.

In the manufacture of automobile bodies of various makes it is customary to use what is known as mill run glass, or glass which is not assorted as Ito thickness, and, there-4 fore, varies substantially in this respect. It is desirable thatthe force offrictional engagement of the guides with the glass shall be uniform' under all conditions, and, as metal guides of the type above referred to are usually Ymade. unl process, so that the force of frlctional engagementof a guide with the glass varies according to the thickness ofthe glass, some means for compensatin for the variations which 4occur when mil run glass. 1s employed, is practically essential.

While I have disclosed such a means 1n my pending application -Serial No. 502,333 this means is open to the objectlon that adjustment cannot be made while .the glass is A ion forthe glass in position.

I accomplish these objects in the` manner hereinafter described and as illustrated' in drawings in which Fig. 1 1s a si erele'vation, artly in central vertical section, of a win ow guide embodying my invention.

Fig'. 2 isa transverse section thereof on an enlarged scale. v

ormly, by a rolling these parts together.

" .Fig 5 is a similar view at line y--y of Fi 3. 'f `ccording to my invention the guide is formed from a strlp of-thin resilient metal bent to provide a base 1 and side guides 2 and 3, the side guide 2 being connected to the base. portion by extending the base laterally to form a semi-cylindrically sha ed portion 4, which projects beyond the slde in the form of a bead. The base is also extended laterally beyond the guide 3 and is bent semi-circularly to form a resilient portion 5, which is connected to said guide 3 by a reversely extending portion 6, which normally extends divergently with relation to the base from stud/portion 5. The

'edge portions of the guides 2, 3 are each rolled inwardly to form rounded, or beaded edges 7 and 8, for direct engagement with the 'glass as disclosed in mysaid pendinglv to provide a glass engaging .portion 10,

,which terminates adjacent the guide 3. A

yieldable arm is thus provided which extends laterallythe entire length of the guide.v The inclined portion 6 is provided with a seriesv of holes 11, which may be formed at any convenienttime in the manufacturing operation, and to connect the base 1 and foot 9, tongues 12 and 13 are simultaneously punched out of said base and foot respectively opposlte each hole 11 and their are bent over ia't on each other and on thefoot` as shown in Figs-4 and 5, so as to clench The windowf casin or pillar 14 is provided with the usua groove or rabbet to\ receive the guide strip, and, where a metal covering 15 is employed, itis shaped to provide a recess 16-in one side and at the bottom of the groove, which extends throughout the length thereof, and in which the bead 4' of the guide is located. A moulding 17 is provided to form the other side of the groove and is secured in position. by screws 18. The moulding is provided with a rabbet or recess 19 at its inner front side which is adapted to receive the bead 5 and inclined varied to secure different results.

portion 10 of the spring portion 6 oi. the a'uide. The relative formation ot'the molding and guide strip may be It may be such that when the side guides 2, 3, are separated to their fullest extentmby their normal spring action, they will be adapted to receive a sheet of glass of the greatest thickness which is likely to be inserted. To apply the desired frictional force thereto under such conditions, vwhen the. molding 17 is secured in position the attaching screws are only turned in :Ear enough to bring the bottom of its rabbeted portion 19 into engagement with the inclined portion 6 of the guide strip.4 It, however, the normal separation ot the guides is such' that the force 4of rictional engagement with glass of the greatest thickness is less than that desired, then the molding will be forced against the inclined portion 6 by forcing the screws 18 in to a greater extent, thereby causing the guide 3 to be swung inwar for example, from the dotted line to the -full line position of Fi 2, so that what may be considered as the inltial set of the guides will be changed. That is, the guides are adapted to yield to an extent from the position in which they are set to provide the desired force of frictional engagement and allow for irregularities or variations in thickness of the glass which is inserted therein.

'It will be apparent that'with the above, described arrangement the initial set ofthe guides may be varied to correspondto all variations in thickness of the glass, so that under all conditions the force of frictional engagement of the guides with the glass will be Practicallly1 uniform.,` Also that 'the adjustment of t e initial set ofthe guides may be accomplished after the glass has been placed in position between. the guides, so that the desired adjustment may be much more quickly and accurately secured than if it was necessary to remove the glass each time the guides were to be readjusted.

As the beads at each side of the guide strip are firmly engaged by portions of the casing or illar, it will be apparent that the strip will e' securely held in position without the necessity of employing other securin means.

en the Glass is in position between the guides, its ednge will be vengaged by the end arm 9 which will provide an eiective cushion therefor.

I claim:

1. A window glass guide consisting of a strip of resilient sheet metal bent to provide a base and a pair of side guides projecting therefrom in position to engage opposite sides of the lass, said base having a lateral extension an a reversely extending connection between said extension and the inner end of one of said guides, said connection nennen Y being yieldable towards lsaid -base and having an outer tace arranged for clamping Yinitial set of its guide.

3.`A window glass guide consisting of a strip of resilient sheet metal bent to provide a base and a pair ofside guides projecting therefrom in position to engage opposite sides 'of the glass, said base having a lateral extension and a reversely extending connection between said extension and the inner end of one of said guides, said connection being yieldably supported by said extension .at a distance therefrom to permit depression of Saidconnection by engagement with the vouter side thereof to vary the initial set of the guide which it supports.

V 4. A window glass guide consisting of a strip of resilient sheetmetal bent to provide abase and a pair 'of side guides projecting therefrom in position to engage opposite sides of the glass, said base having a lateral extension and a reversely extending connee tion between said extension and the inner Vend of one of said guides, said connection being yieldably su ported by said extension -at a distance there romto permit depression of 'said connection by engagement with the outer side thereof to vary the initial set of the guide which it supports, and a spring arm aving one end portion attached to said base extension'between the'same and said reversely extending connection, and said arm being extended Vbetween said side guides in position foryieldable engagement with the edge of the glass disposed between said guides.

5. A window glass guide consisting of a strip of resilient sheet metal bent to provide a base and a pair of side guides projecting therefrom in position to engage opposite sides of the glass, said base having a lateral extension at each side and a reversely extending connection between each base extension and each side guide, one of said metal strip having a base portionseated on the bottom of said groove and two side lguides extending outwardly therefrom, said ase groove and having a reversely extended portion resiliently connected thereto and to the adjacent side guide, and a clamping -strip havingadjustable means engaging the casing for forcing the strip against said reversely extended portion to vary the initial set' ot' said side guide,

7. ln combination With a Window casing having a longitudinal groove and a l'atera recess leading from one side thereof` at its 15 bottom, a resilient sheet metal Window guide being extended laterally beyond the .disposed in said groove and formed to provide a base and oppositely disposed side guides extending outwardly therefrom, said base being laterally and reversely extended at each side to connect the same to the adjacent lside guide, one extended portion being disposed in said recess and the other having a yieldable connecting portion with lthe lcorresponding gulde and a molding strip engaged with said yieldable portion and adjustably connected to the casing to vary the normal positiony of its guide.

In testimony whereof, have signed my name to this speciiication.
